Abstract
The invention discloses a kind of steel positive bucket face piston ring being coated with molybdenum bisuphide coating.This steel positive bucket face piston ring being coated with molybdenum bisuphide coating includes steel substrate, chromium coating and molybdenum bisuphide coating, the axial cross section of described steel substrate is rectangle, a chamfering it is respectively arranged with up and down inside described rectangle, described rectangle lateral profile is circular arc, described chromium coating is coated with described steel substrate, and described molybdenum bisuphide coating is coated with chromium coating.The steel the being coated with molybdenum bisuphide coating positive bucket face piston ring of the present invention has that frizing is effective, wear-resisting, initial stage self lubricity and the not advantage such as scuffing of cylinder bore, meets the development trend that piston ring is following, wide market.
Description
Technical field
The present invention relates to automobile engine spare and accessory parts field, particularly relate to a kind of piston ring.
Background technology
Piston ring is widely used on various dynamic power machine, such as steam engine, diesel engine, gasoline engine, compressor, hydraulic press
Deng, it is widely used in automobile, train, steamer and yacht etc..General piston ring is arranged in the annular groove of piston, and piston ring is that fuel oil is sent out
Core component within motivation, it and cylinder, piston, cylinder wall etc. completes the sealing of fuel oil-gas together.
Piston ring effect includes sealing, regulating machine oil (control oil), heat conduction (heat transfer), guiding (supporting) four effects.Seal
The gas not allowing combustor drains to crankcase, and the leakage rate of gas is controlled at bottom line, improves the thermal efficiency.In Modern High-Speed
On electromotor, pay attention to piston ring especially and control the effect of oil film.Heat conduction is, by piston ring, the heat of piston is conducted to cylinder sleeve,
I.e. play cooling effect.Think that piston is kept in the cylinder by supporting piston ring according to reliable data, prevent piston direct with cylinder wall
Contact, it is ensured that piston smooth movement, reduces frictional resistance, and prevents piston knock.Many a kind of coating outside piston ring at present
Or coating, simple chromium coating can be wear-resisting, but easily scuffing of cylinder bore；Self-lubricating when simple molybdenum bisuphide coating is initial stage break-in, but
The most wear-resisting, function shows slightly single, along with the development of engine technology, the function of piston ring is proposed the highest requirement,
It is accomplished by researching and developing the piston ring with plyability function.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of steel positive bucket face piston being coated with molybdenum bisuphide coating
Ring, not only has the advantage that scuffing of cylinder bore, initial stage do not have self-lubricating function and rub resistance to wear and tear, and frizing effect is strong and is difficult to stuck
Etc. advantage.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide one to include steel substrate, plating
Layers of chrome and molybdenum bisuphide coating, the axial cross section of described steel substrate is rectangle, is respectively arranged with one up and down and falls inside described rectangle
Angle, described rectangle lateral profile is circular arc, and described chromium coating is coated with described steel substrate, and described molybdenum bisuphide is coated with
Layer is coated with chromium coating；
Described chamfering is 40-50 degree；
The thickness of described chromium coating is 110-140 micron；
The thickness of described molybdenum bisuphide coating is 5-10 micron.
Saying further, described chromium coating is chrome-base ceramic composite plating layer.
Saying further, described molybdenum bisuphide coating is sprayed coating.
Saying further, the periphery of the described steel being coated with molybdenum bisuphide coating positive bucket face piston ring has coated
The chromium coating stated and described molybdenum bisuphide coating, upper surface, lower surface and inner headed face without.
Saying further, the center of circle of described circular arc is in the plane high apart from described piston ring upper surface one semi-ring.
Preferably:
Described chamfering is 45 degree；
The thickness of described chromium coating is 120 microns；
The thickness of described molybdenum bisuphide coating is 8 microns.
The invention has the beneficial effects as follows: the steel the being coated with molybdenum bisuphide coating positive bucket face piston ring of the present invention, structure
Rationally.It is effective that the positive bucket face structure used makes piston ring have frizing, is difficult to stuck advantage, makes manufacturing chromium plating simultaneously
During layer, adhesion between piston ring plate and sheet, easily separated, it is simple to operation.The chrome-base ceramic contained by chromium coating used more improves
The wearability of this coating and on-deformable ability.The more important thing is that molybdenum bisuphide coating uses the method for spraying to prepare, side
Method is simple, equipment is simple, and low cost.The steel the being coated with molybdenum bisuphide coating positive bucket face piston ring of the present invention, has
Frizing is effective, wear-resisting, initial stage moistness and the not advantage such as scuffing of cylinder bore, meets the development trend that piston ring is following, and market prospect is wide
Wealthy.
